CHANGE-GEAR FOR MECHANICAL LOOMS.

No. 930,707. Specification of Letters Patent. Patented Aug. 10, 1909.

Application led. February 18, 1907. Serial No. 357,966.

Lever l() is pulled to the left by bell crank 14, and lever 9 to theright by bell crank 12, 13'when the wires 17 are pulled.

On the main shaft 13 of the loom, Fig. 3, is provided an eccentric 19,from which by aid of link bolts 21 and 22 and rod 20, lever 23 of thenew gear is operated. The latter is rigidly fitted to the shaft 24,running in bearings in the sides of the frame 25 and 26, Fig. 2, andcarrying besides lever 23 levers 27, 28. rIfolbolts 29 and 30 of levers23 and 27 are linked the rods 31 and 32, to produce a connection withthe blade fitted with ins 33 and 34 and oscillating in the slots inframe sides 25 and 26. In these sides are also arranged the shafts36-39, carrying the Vsingle armed levers 40-43 and the double armedlevers 44-47. rl`he latter are connected with the lifter-levers 48-51 bywires 52l and a spring 53, so that the lifterlevers to which the lifters5457 vare linked by means of bolts 58 are forced by the action of thespring againstpthe sto 59 provided between the frames. For eac lifter athree armed lever 60, 61, 62'is provided, supported on shaft 63. 0nshaft 64 moves loosely the tumbler 65, 66, which by its own weight isable to hold levers 62 by means of cross piece 66 in their positionfarthest to the right. The numbered disks are attached to the shaftsl67. at theplaces marked X, at the back of said shafts are the cranks 63which by means of rods 69 are linked to levers 60.

To all whom it may concern:

i Be it known that l, FRANZ Louis WGHT- LER, director, a subject of theKing of Saxony and German Emperor, residing at 5 Grossenhain, in theKingdom of Saxony and German Empire, have invented certain new anduseful Change Gear for Mechanical Looms, of which the following is aspecification.

10 rlihe purpose of the present invention is to l allow of working onmechanical looms without change-card, the change being operated by handby aid of numbered disks, handles or other suitable appliances. Hereby.the shuttles will have to always enter the same change-cells on eachside of the lloom 'and may not be shot crosswise as is the case whenchange-cards are used.

ln the accompanying drawings, Figure 1 is a front elevation and Fig.4 2a plan of the device. Fig. 3 is a front elevation of the device togetherwith a change-gear, in which the shuttle boXes are adjusted by twotoothed drums turning in opposite directions. Fig. 4 is a side elevationof Fig. 3.

The Figs. 5, 6, 7 and 10 show strips of paper,

used for the loom. Fig. 3 illustrates the way of such strips lof paper.Fig. 9 shows a groove, in which said strips are introduced.

ln Fig. 3 the right shuttle boX is shown partly removed, in Fig. 4 theknown liftinggear with the shuttle-box has been omitted.

The new arrangement, which is arranged above the loom, is fitted withnumbered disks, handles or other suitable appliances and has the samenumber of disks, as shuttles are used for weaving. For reason of greatersimplicity of the description and the drawing only four shuttles havebeen employed, wherefore only disks Nos. 1-4 have been provided. ln cell1 (Fig. 3) there is shuttle No. 1 and in cell 2 shuttle No. 2, in cell 3shuttle No. 3 and lastly in cell 4 shuttle No. 4. Cells 5 and 6 areempty, cell 5 temporarily receiving' shuttles 3 and 4, cell 6 theshuttles 1 and 2.

The change-gear Fig.

a manner, that by rovision of springs 7 and 3 the levers 9 an 10 aregeared in known manne-r so that the empty cells are brought in line withthe lay race from the first. On

the frame-pin 11 bell cranks 12, 13 and 14, 15

are pivotally arranged, which are connected with levers 9 and 10 bymeans of rods 16.`

On the bosses 70 of levers 61 rest the lifters 54-57 which are raised sofar by the springs 71 acting on lever 61, until the arms 60 on the crosspiece 72 reach a stop and come into the position shown by the dottedlines. The numbered disk 1 belongs to lever 61 beneath lifter 34, disk 2to lever 61 under lifter 55 and so on. If now disk 1 is turned say tothe right',

until lever 61 comes m contact with crossbar 72, the respective lifter54 will be lowered to the blade 35 and carried along by the latter inits motion from left to right, whereby at the same time shaft 36 ismoved in direction of the arrow 73 and will by means of connecting wire7-4, acting on lever 40, a bell crank 76 on the frame pin 7 5,'Figs.

bring cell 1 in known 3 and 4, and wire 17 manner in line with thelay-race. As long as this lever 62 is held by the web 66 of tumbler 65the lifter 54 will be carried along at 111e each stroke of blade 35,cell 1 remain 1n 4 is arranged in such with the lay race and shuttle No.1 be shot continuously back and forward. lf however another disk isturned to the right by the upper beveled surface of lever 62 the web 66on the tumbler 65 will be raised, so as to release the former one andhold the one turned last.

In order that the weaver may only be able to turn the disks in theproper moment, and as the case may be for two, four or more successiveshots per shuttle, the following arrangement is provided: 0n frame bolt77 is arranged a lever 78 with bolt 70 and roller 80. The lever 78 iselastically connected with the frame 26 by means of spring 81. To saidattached a hook 82 on which the branch 83 of tumbler 65 will rest,wl'iereby a turning of the adjusted disl s is prevented.

t every second shot the support is removed, by the lever 78 being movedin direction of arrow 84, until hook 82 is removed from the path oflever 83. This is obtained by the following arrangement: On the bolt 77is also rigidly mounted the lever 88, which is linked by means of rod 89and bolts 90 and 91 to lever 28. In lever 88 is fitted a bolt 92. rlhelatter carries the parts as used in a shalt machine with pasteboardcards, namely a wheel with ins 93 in which catches the reversing hoolk911 fitted on frame bolt 95,' cylinder spider and 98 and the t each 96with cylinder holders 97 thereto attached spring 90. stroke of frame 88to .the right by Y th of its circumference in direction of the arrow100. The lantern carries three pins 101, 102 and 108 and as soon as at astroke one of said pins 101`103 strikes against the roller 80, lever 78is taken along into the position Fig. 3 for releasing the disks and isupon the return of lever 88 instantly returned into its originalposition by spring` 81.

Until now l have described the arrangement for sending the shuttle twosuccessive shots through the shed. It may however also be shot singletimes, and to obtain this, the web 66 is permanently released, byremoving the hook 82 or fixing lever 78 in its farthest position indirection of lever 84. Care must be taken, that wires 17 are soconnected with bell cranks 12`15 that by turning the disk 1 the shuttlecells 1 and 3 are adjusted in line with the lay race, on turning thedisk 2 the cells 5 and 6, and on turning the disk 3 the cells 2 and 4'.Three shuttles may be used, shuttle 1 entering cells 1 and 8, shuttle 2cells 5 and 6 and shuttle 3 cells 2 and 4.

A strip oi' paper, the same as used in Morse telegraphing apparatus,must be used lor each loom. On it the colors and the numbers of shotsare marked successively, as they are to be made in the fabric. Thegraduation on lever being said strips in. direction (L l), Fig. 5, isthe same iii all mills, the distance c, `Fig. 5, giving the number oilshots to be made with the same color. lt is once marked on the sti ip,see Fig. 6, or the color or the shuttle: are numbered, see Fig. 7. Thestrip is introduced in a groove 1, FigsS and Sl, directly at the edge ofthe cloth beam on the side where the numbered disks are and moved at thesame time with. the finished stull, l'rom beam 2 in di ree tion ol'arrow 3. Generally the weave will read where the arrow 4- points to, thel'ollow ol' the shots, and when a new cross l ine. a reaches this place,he must start the disk on the automatic gear corresponding with therespective 'following color. lt must however be mentioned here thatcertain mills use strips as shown in Fig. 10 and imlicate hcneath theline the number oll shots, which are to be made in the fabric. ln suchmills it is supposed that the weaver counts the shots while weaving,which is however not always done.

The strip ol' paper comes l'rom a roller 4 on a i'ranie 5 and passesover rollers 6, 7, 8 and 9. The rollers 6, 8 and 0 are arranged to turnonly on jl'raine 5. lloller 7 however can rise and fall so as to keepthe paper always tight. It is pivoted to a bar 10 which swivels around aframe bolt vided a set piece 13, which by means ol` holt 15 is linked tolever 14. At the lower end olI said lever is hinged by means ol' bolt 10the balance 17 with rubber rollers 18 and 10. 0n bolt 15 is provided aspiral spring, which is so arranged that rollers 18 and 10 are pressedin direction oiA arrow 20 against the cloth beam 2. iis the paper stripis therebetween, only so much is unrolled lrom the roller 4 as finishedl'abric is ren'ioved l'rom the cloth beam. The paper strip passes overroller 21 and beam 22 and is rolled up on roller 23. To said roller 23is attached a roller 26 around which a cord is wound. The other end elthis cord is rnn over a roller fastened to the ceiling oll the room andis provided with a small weight. Vilhcn this weight has worked down tothe lloor, l. paper strip being rolled up, the cord is wound afresharound roller26. The paper on roller 23 is placed on bolt 27 andv-.orkcd oil' again.

he paper strip may also he suitably called pattern strip.
